The double shooting happened on Center Street near Brentwood Drive, between U.S. 1 and Nova Road around 5:40 a.m., according to police.

The police chief said the boy was shot in the torso and the infant, a 5-month-old girl, was shot in the hand with an AK-47.

The baby girl was airlifted to Orlando Health Arnold Palmer Hospital for Children and doctors were able to save her hand, Capri said.

“She’s young enough she’ll be able to heal,” Capri said.

Terrance H. Young, 37, who has a relationship with the children’s mother, was taken into custody at a residence on Division Street, police said.

Capri said authorities had previous history with Young and tracked him to an area he was known to frequent.

Police said Young fled in a blue Land Rover after the shooting, but his SUV was found near the intersection of Whitehall and George streets. Young was found on Division Street about 30 minutes later, police said.

Prior to his arrest, police said Young attempted to set the home he was hiding in on fire but was not successful.

Capri said Young appeared to be on drugs and he was “babbling and incoherent” when he was taken into custody. The chief described the suspect as “a deranged individual armed with an AK-47.”

The victim’s great uncle, Antonio Harrison, said the 10-year-old is survived by a twin sister.

“It takes an evil person to kill some kids,” Harrison said. “I’ve told her to get that guy out of the house. She wouldn’t listen. He’s said he’s from Miami and would do want he wants to do.”

During a news conference Thursday, community advocates warned parents to be careful who they bring into their homes and around their children.

“Parents, you must watch your children, you must watch who you associate with, who you bring into your home,” said Cynthia Slater, President of the Volusia County NAACP chapter.

No other details, including what led up to the shooting, have been released.
